CABLE-TERMINAL.

Specification of Letters Patent.

Patented July 4, 1911.

Application filed July 15, 1909. Serial No. 507,773.

- The principal objects of my invention are,

to provide an improved cable terminal as will be hereinafter more fullydescribed; and to provide an improved construction in porcelain cableterminals of the character specified. Other objects will be apparentfrom the following specification.

Heretofore it has been customary to make protected cable terminals ofthe closed-head type of either cast metal or sheet metal, and provide onsuch cable terminals fanning strips or distributin strips of either.wood or of metal. Such cable terminals are generally expensive to makeand the metal employed in their construction is objectionable undercertain conditions. I

In the improved cable terminal of this invention I have provided aprotected cable terminal of the closed-head type made of two porcelainhalves suitably placed -to- 85 gether, these halves having extendededges thereon adapted for fanning strips or distributing strips. Such acable terminal, it will be readily seen from the following description,is very simple in its construction, very substantial and practical, andelimi- "nates the large metal parts used in older forms of cableterminals.

3 In the accompanying drawings illustrating the preferred form of myinvention,

: cable terminal, with some of the lower porti'ons broken away; and Fig.2 is a plan view of Fig. 1, with some of the portions removed. -Likecharacters refer to like parts in the 50. several figures.

By. reference to the drawings, 1 is a circular base plate having arearwardly-eX-' tending portion 2 adapted to be mounted to a suitablesupport. The head of the cable 5 terminal, comprising two porcelainhalves 3 3, is mounted on the base plate 1 by means Figure l is'a sideelevation of the improved of angle irons 4 4 and bolts 32 32 and 33 33,the halves 3 3 being suitably bolted together by bolts 5 5 and 6 6 andhaving suitable gaskets 7 and 8, preferably of felt, therebetween asshown. Between the head 3-3 and the base plate 1 there may be placed asuitable gasket to form, a tight joint between these parts. At thetop-ends of the halves 3 3 may be placed a top plate 34, suitably heldin place by bolts 31 31, to cover the top end of the cable terminal.This plate 34, however, may be dispensed with if desired.

Each of the porcelain halves 3 3 is provided with a forwardly-extendingedge 9 and a'rearwardly-extending edge 10 formed integral therewith, theedges 9 9 and 10 10 serving to support a cylindrical cover which may beplaced down over the cable terminal and the circular base plate 1 in amanner well understood. Each of the edge extensions 1O 10 is providedwith a series of holes 11 11 therethrough serving to accommodate aerialconductors leading up through an opening 12 in the base plate 1 and outthrough the holes 11 11 to suitable terminal members which will behereinafter described.

Each of the porcelain halves 3 3 has two vertical rows of projections 1313 thereon formed integral therewith, the front row of projections 13 13carrying a series of fuse clamping springs 14 14 and a series oflightning arrester springs 15 15, and the rear row of projections 13 13carrying a series of fuse clamping springs 16 16. The

springs 14 14 and 15 15 are held in place by hollow binding posts 17 17which extend through the walls of the portions 3 3 into the opening 18of the terminal head formed by the two halves 3 3 being placed together;these posts 17 17 being riveted over as at 19 19 against suitable metalwashers 2O 20,

preferably of a soft metal such as lead, to securely hold the partstogether.

arid 16 16 in a manner well understood, andalso a series of lightningarresters 24 24 placed between the corresponding springs The springs 1616 are suitably held in place by 15 and ground strips 25 which areattached to the porcelain halves 3' 3 by suitable pins or rivets 26 26.Each of the ground strips 25 25 is provided with a series of tongueportions 27 27' adapted to fit in grooves of the corresponding lightningarresters and thereby hold same against lateral movement, in a mannerwell understood. It will-readily be understoodthat the fuses 23 23 andlightning arrcsters 24 24; may be removed, or replaced by others, asdesired.

The base plate 1 carries a nozzle 28 the upper end of which ispreferably formed outwardly against the plate 1. as shown at 29 tosuitably secure the nozzle28 in place. The nozzle 28 opens into theopening 18 of the terminal head and is for accommodating cableconductors extending up through the nozzle 28 and the base plate 1 intothe opening 18 of'the terminal head, in a manner Well understood. Thecable conductors from the opening 18 are distributed out through thehollow binding posts 17 17 in a manner well understood, and are securedto the outer ends of these posts 17 17 by solder which tightly seals theopenings in the posts 17 17-. I The spring members 14 14 and 16 16 haveinwardly-projecting lugs 30 30 fitting over the projections '13 13 asshown, to prevent these spring members from turning on their mountings.

When it is desired to separate the halves 3 3 of the cable terminal fordistributing the cable conductors out through the hollow binding posts17 17, such separation may be accomplished by loosening or removing thebolts 5 5, 6 6,-31 31 and 32 32, vwhereupon the halves 8 3 may bereadily separated as desired. Vhen the cable conductors have beendistributed as desired, the parts may be again bolted together asdescribed to condition the terminal foruse. If desired, a suitableinsulating compound or material may be poured into the opening 18 of theterminal head to suitably seal the cable conductors in the terminal.head and prevent any moisture from penetrating into the end of the cableor into the coverings of the cable conductors.

It will be readily seen that the projections 13 13 greatly increase theinsulation between the adjacent spring members of the cable terminal,because they provide an increased extent of surface between suchadjacent spring members.

I do not wish to limit this invention to all of the particular detailsherein set forth, as various modifications of same may be made withoutdeparting from the scope of the appended claims.

lVhat I claim as my invention is:

1. A cable terminal of the character set forth having a head portioncomposed of two halves separately secured together to form the head andeach having front and rear vertical edges for forming guides for acover, suitable protective apparatus mounted on the said halves, the tworear edges of the said halves being separated from each other to formtwo separated supports for the cover in the rear of the head, and thetwo front edges of the said halves being secured together to form but asingle support for the cover in front of the head.

2. A cable terminal of the character set forth having a head portioncomposed of two halves separably secured together to form the head andeach having front and rear vertical edges for forming guides for acover, the two rear edges of the said halves being separated from eachother to form two separated supports for the cover in the rear of thehead, and the two front edges of the saidhalves being secured togetherto form but a single support for the cover in front of the head.

As inventor of the-foregoing I hereunto subscribe my name, this 10th dayof July, 1909.
